Looks great. If it were me I would put the stock in front the side rather than the front...unless of course you only plan to make small items...just my preference.
I used a screw on cap on my first forge as a ash dump and I welded a small handle onto it...a LOT easier to turn when it did get stuck. On my latest forge I have an exhaust flapper with a counter weight (RR spike)...I like it a lot better.
And, as already mentioned, your horseshoe is oriented correctly! :)
